should make sure that the devices connected to the transceiver ports are also configured to
Auto. At a minimum, make sure the configurations match.
NOTE:
For improved cable management, install the GigT/SFP and GigT/SFP+ combination
modules on the left side of the chassis. This will improve access to the uplink ports when
the RJ45 cables are retained in the cable manager.
Module installation notes
The following cases automatically result in a change to the running-configuration on your switch.
Replacing a module with another module of a different type and then rebooting the switch
Installing a module in a slot that has not previously been used (including when you install a
module and apply power to the switch for the first time)
If you want to save such changes to the startup-configuration file, use the write memory command
in the switch's command line interface. This causes the switch to use the current new hardware
configuration for subsequent reboots. (The switch always reboots from the startup-configuration
file.)
One of the features of your 5400R zl2 switch is the ability to "hot swap" the switch modules. You
can install, exchange, or remove modules after the switch has been powered on. Whenever a
module is installed during this process, it is initialized and tested for correct operation. During
this process, the switch Self Test LED is on. If you hot swap another module while the switch is
initializing and testing the first module, it is possible to cause the first module or the entire switch
to be reset.
To prevent the modules or switch from being reset when you must hot swap multiple modules,
follow these simple precautions: Before removing or installing any modules, make sure that all
network cables are disconnected from the module. Do not remove any modules from the switch
while the switch Self Test LED is lit.
Installation Precautions
WARNINGS
Devices installed in a rack or cabinet should be mounted as low as possible, with the
heaviest device at the bottom and progressively lighter devices installed above.
The rack or cabinet should be adequately secured to prevent it from becoming unstable
and/or falling over.
Ensure a cover plate is installed on any empty switch power supply or module slot.
A cover plate is required for safe operation, and to ensure proper switch cooling.
Never have more than one power supply or module slot uncovered at a time while the
switch is powered on.
To avoid energy and mechanical hazards, never allow any part of your body, jewelry,
tool, or other foreign object to enter any module or power supply slot.
This unit may have more than one power supply cable. To fully power down the switch,
you must disconnect all power supply cables from the unit.
When the HPE 5412R zl2 switches are operating in the high-line voltage range (200 -
240 V), the switch may have high leakage current depending on the power supply
configuration. Safety leakage current per cord for the three available 5400R zl2 power
supplies is 0.85 mA maximum, regardless of the power supply model. When more
than four power cords are installed in the chassis, the leakage current safety limit
threshold of 3.5 mA may be exceeded. If the switch has four or fewer power cords
installed or if the equipment is operating in the low line (100 - 130 V) voltage range,
